関の空燃比制御装置。 The fuel supply system calculates the fuel injection amount using electronic control so that the air-fuel ratio of the air-fuel mixture taken into the engine matches the target air-fuel ratio using an air-fuel ratio sensor that detects the air-fuel ratio according to specific components in exhaust gas. In an air-fuel ratio control device for an internal combustion engine to be controlled, an engine load parameter and an engine speed are detected by a detection means, and a correction value corresponding to the engine load parameter and engine speed detected by the detection means is used to control the electronic control unit. An air-fuel ratio control device for an internal combustion engine, characterized in that the output value of the air-fuel ratio sensor or the air-fuel ratio information determined from the output value is corrected.
